This is a children's story of the daily and adventurous episodes in the lives of Renee and Albret, young twin sisters in a seventeenth-century, French Protestant family. The story follows the twins and the rest of the Martineau family as they work, worship, commune, and suffer persecution together. The story aims to portray the ideas and historical details common to Huguenot life in La Rochelle, France, 1685, a tragic year whose final quarter brought the full wrath of Louis XIV.
